GOLF CLUB.

The improved golf club structure of the resent invention is of the genera-l type disc osed in my prior patent No. 1,551,563

issued under date of Sept.. 1, 1925 wherein a rubber sleeve is interposed between the head member and the lower end portion of the' shaft. In addition to providing a -desirable resiliency between the head and shaft '30' portions of the club, the rubber' sleeve member positioned under compression between ythe head and shaft has proven to be highly desirable by reason of its high securing value in providing a vfirm and durablev attachment between the parts. The present invention comprises further improved features of construction adesigned to facilitate the assem- "bling of the structure with resulting economy of manufacture and to possess other 80y features and advantages with reference to lirmly'securing the parts in position while vretaining the desirableresiliency aforesaid. The described'and other advantages 'of my lim rovedconstruction will be more readily 35 un erstood by reference .to the accompanying drawing wherein like reference characters are applied to the corresponding parts in the'several views.

lIn the drawings:

40 Fig. 1 is a view in elevation illustrating a club of the driver or brassie type made in laccordance with m invention.

' Fig. 2 is a detai view of the lower portion of the club embodying the features of my invention and shown partially in cenj f tral vertical section.

a desirable modified construction 'adapted for incorporating features of the present implrolyements with a wooden bshaft type of c u Fig. 6 is a detail sectional View showing a further modified structure wherein the bore of the head is tapered fro-m both ends. no

In the drawings, wherein there is shown a suitable embodiment ofthe features of my invention, lindicates the usual shaft having the handle ortion 2 at its up er extremity and having the usual club cad 3 05 mounted u on the reduced lower end portion 4 of the s aft; The head properis of a lproved form having the usual upward y curved neck portion 5 integrally formed therewith and provided with a longitudinal V'l0 cylindrical bore 6 for the reception of the lower shaft end portion.

The lower end of the shaft, as illustrated; is fitted within the bore and a sleeve of rubber or 'other suitable resilient material 75 is fitted within the bore throughout the length thereof and interposed' between the shaft and the wall of the bore 6 to 'permit of relative movement and resilient action between the club head and the supporting l end of the shaft. The resilient sleeve is shown at 7 and extends from the lower'end of the bore upwardly for the full length of the bore and slightly above if desired.

In accordance with my resent improve- 86 ments the steel shaft may e made by first forming a blank of sheet metal as shown in Fig. 5 which progressively diminishes in width toward one end the end forming the lower portion of the sha toapoint-noted at 00 the remaining or extreme end portion being of uniform'width as here shown for a length substantially one half that of the head bore. The end ortion lof the shaft blank is further provi ed with the longitu- 05 dinally extending cut or slit 9 and the shaft is formed b v rollin over of the blank and uniting the ongitudinal side edges by a suitable welding operation. The resilient member or rubber sleeve may normallyjbe of )no tubular form and of uniform thickness of its wall and in the assembling of the device it desirably has an adhesive or rubber "cement applied to its external surface for firmly securing it to the head portion of the club. Upon being positioned within the bore of the head, as shown, the shaft formed in' the manner described and having its lower portion of the form as shown in Fi 3 is forced within the rubber sleeve where y the taper of 11a will operate to effect a desirable coi'nnissionef the upper portion of the rubber 'leeve o ',lient member, l/Viththe parts in final pontiou, a wedge element or tapered plug` l() forced or driven upwri 1dly into the lower split portion of the shaft end whereby this lower end portion ol' the shaft is spread or expanded into flared form having its wall in opposite inclination to that of the upper shaft portion as best illustrated in 4c. rlhe insertion of the plug l() in similar manner effects a compression of the resilient sleeve member with respect to the lower end portion thereof from which it results that the head and shaft are firmly' secured against 'lisplzuzeinent. As will be understood, a suitable cement may likewise be employed between' the engaging surfaces of the resilient sleeve and thc-shaft for ohtaining ai'lditional security. The tapered plug member 10, as here shown of truncated conical. form, may desir-ably be made of aluminum or of suitable hard wood as preferred. l

Tl'iere is thus produced a golf club of im l n tue shari,

proved construction having a resilient sleeve.'

element incorporated therewith so as to provide a desirable resiliency between the head and shaft. rThe structure accordingly provides for rebound both in the vertical and inthe torsional sense s0 that while possessing the advantages of the steel shaft, a more effeetive strolre is obtained and which in its action simulates the elastic and yielding c tfect attained with the better grade of wooden .modifications may be made without departing from the scope of the invention as delined in the `appended claims. As illustrative thereof, l have shown in Fig. 6 a suitable modified structure wherein the bore of the head portion has its wall tapered or inclined inwardly from its upper and lower ends thereby contributing a mechanical bondingefect giving additional holding value by reason of the interlocking relation of the parts.

Having described my invention, l claim:

l. l golf club comprising a shaft and a.

lmember being formed with a connectingl portion havingy a bore to receive the shaft end, a rubber sleeve iitted within the bore and interposed between ,the wall of the bore and the shaft7 said shaft being of tubular meta-l of progressively decreasing diameter toward its lower end andA itted within the sleeve to compress the latter and a tapered wedge member forced into the lower end portion of the shaft for expanding the shaft end to secure the parts and to effect compression of the sleeve. v

A golf club comprising a 'shaft and a head member mounted thereon, said head member being,T fori'ned with a connecting portion having a bore to receive the shaft end, a resilient. sleeve fitted within the bore and interposed between the wall of the bore and the shaft, said shaft being of tubular metal of progressively diminishing' diameter toward its lower end and fitted withinthe sleeve to compress the latter and havingq its lowermost portion split and a tapered wedge element forced within the lower slit Dertien. of the shaft for expandingfthe shaft end to secure the parts and tto effect compression of the sleeve member.

d. A golf club comprising a shaft and a head member mounted thereon, said head member beingF formed with a connecting portion having a bore to receive 'the shaft end, a rubber sleeve tted within thebore and interposed between the wall ofthe bore and the shaft, said bore having its wall inclined inwardly from its upper and lower ends to be of reduced diameter at its central portion, said shaft being of tubular metal and a ltapered wedge element fitted within.y the lower end of the shaft for expanding,h the shaft end portion and to effect compres'- sion of the sleeve.

Signed at Newark, in the county of Essex and State of New Jersey this 7th day of December, A. D. 1926.
